Model infection
An infectious disease is said to be endemic when it can be sustained in a population without the need for external inputs. This means that, on average, each infected person is infecting exactly one other person (any more and the number of people infected will grow sub-exponentially and there will be an epidemic, any less and the disease will die out). In mathematical terms, that is: The basic reproduction number (R0) of the disease, assuming everyone is susceptible, multiplie… WebMathematical modeling is a valuable tool in the analysis of infectious disease dynamics and to support the development of control strategies for epidemic outbreaks.
